vState of Kentucky, have iuvmited .new and useful Improve-meule in Plastering-illu chilies, of which. the following i5 a speeilii-ation.

The present invention relates to plastering machines, aud the j vrimary object ie to provide novel, simple and etieetire lueur-a that will apply plaster to Walle, the saine operating with speed aud are-uraer, and be ing adjustable to the work to be performed.

A simple ei'ulxuliuieut ot the invention that has proven entirely praetimible, i5 illim- 'trated .in the aeeompauyilug,l drawirrg'e, wherein Figure l is a rear elevation ot' the` ma Chine-. Fig. 2 is a front elevzitfioii, showing' the machine on a supplemental sumiort. Fig. 3 iS a plan View. Figi'. etis a seetioual View on the line o t.' Fig. li.

Similar re't'ereiiee uuluerals designate cui responding parte in all the liguria; of the drawings.

In the embodiment. disclosed. a siuxfipurtfjing trame is emplrjiyei'l, eouiprieiue; a vbaat: i. on which are mounted roruer standards these standards being' preferably' made ol' wooden stripe Sl, against'r the iuuer Ytarea ut' Ywhich are fastened (channel irons lt). The upper ende of' the .stunclarilel are eouuerted by longitudinal and transverse bam ll. The said channel irons l0 eomlitute guides l'or a vertically movable carriage that. ia iu thtl form of an open trame l?, having` shoes 'lll thatoperate in said channel irons l0. '.llhe Carriage, in turn. constitutes a` Huppert, aud guide ttor a` horizontally movable warrior, designated as a whole by the realer-euri uu meral tft.

For the Vpurpose oit supporting and uujr ing the eaiiriage l2. rertifral screws 'l5 are jourualecl iii the ends ot' the suppmftiuy,F frame, and boxes lil, secured to the eudr; uit saidcarriage, have threaded eugjaifeuieuts with these screws.

'lhe sermvst, at one oud, are emuu-eted by a aguueltet. ehaiu Q8 passing about Aproel-:ety wheels lfl, lifted to Said -wreuen The other ends of these screws, have loosely jourualed thereon, sprocket u'beelhl 30, around one of which passes a .proeltet rhaiu lll, thatalso engages theolher aud ie: ao d;-;m.--:ed as to cause said wheels` to rotate iu apporte directions. lluteh de virer; 23;? ot' any fadtable olu'uacter are mounted ou the seri-,wu 2t?, and are Connected to a imi-r 21.*, pivoted atv its; center, as shown :it itt, alul so arranged that either sprocket wheel il() eau be clutched to its screw, while the other remainfi uuolutielied. These clutch derivee il are et course iiied to rotate with theI .ai-reus. buty are n'iovable along said eert-uva to alternately loch; the sprocket wheels it? to t' ir respective screws. The apmelaet, 'ehaui .'41 passes about a third remontar! wheel mounted on a seeond driviuggfehzilt 36, journaled lougibudinzilly upou the carriage, and the sprocket wheel 35 can be olutel'ied to andauaelutehed from tzhll.r alia'tt :'36 by au ordinary clutch member 2&7. uetiuited by a lever 8S.
